Get Database From Connection String in MongoDB
The hosts
and settings
to be used are described in the connection string. For this string to be recognized as being in the standard connection format, the prefix mongodb+srv:/
is necessary.
Syntax:
mongodb+srv://[username:password@]host1[:port1][,...[,hostN[:portN]]][/[database][?options]]
The options that the MongoDB connection string offers are as follows.
Options | Description |
---|---|
username |
The username used to connect the driver to Mongo. |
password |
The username used to connect the driver to Mongo. It is an optional parameter. |
host |
It gives the server address to which to connect. |
port |
It gives the port number to use for connecting. 27017 is the default. |
database |
The name of the database driver needs to login to, which is only important when the format username:password@ is used. The "admin" database is used by default if not specified. |
The steps to extract the database name from the MongoDB connection string are listed below.

mongodb
package.Install the most recent MongoDB package from

, a fresh instance of the MongoClient is created, given a URI string.const uri = 'mongodb+srv://sample-hostname:27017'; const client = new MongoClient(uri);
-
Get the database name.
const dbNames = client.db().databaseName;
Full Code Snippet:
const {MongoClient} = require('mongodb');
const uri = 'mongodb+srv://sample-hostname:27017';
const client = new MongoClient(uri);
const dbNames = client.db().databaseName;
console.log(dbNames);
